Summary

This data set is comprised of five files related to the modification and scoring of Index of Waterbird Community Integrity (IWCI) scores for all waterbirds of the Chesapeake Bay. One Excel file (A) contains a list of 100+ Chesapeake waterbird species and their species attribute and IWCI scores. Another Excel file (B) contains case study data from recent surveys of breeding and migratory waterbirds in Chesapeake Bay and shoreline delineations across a disturbance gradient that were used to demonstrate the utility of the modified index. Finally, three supplemental files include an Access database (C), R code (D) and a protocol (E) for running the complex steps to calculate index scores.

Purpose

The purpose of this study is to provide a robust, consistent approach for defining each of the IWCI criteria, and to apply this approach to the suite of waterbird species that may be encountered in the Chesapeake Bay region. We demonstrate the utility of the index by applying it to data from surveys of breeding and migratory waterbirds in seven subestuaries with differing degrees of urban development. This explicitly-defined scoring system will facilitate application to new species in the Bay or new areas beyond this region. By providing these updates and analysis tools, we expect this approach will be much more accessible to new studies and regions, and provides a consistent methodology which can be applied across studies
